- BACKGROUND: Single-center data suggest that the index of microcirculatory resistance (IMR) measured early after heart transplantation predicts subsequent acute rejection. OBJECTIVES: The goal of this study was to validate whether IMR measured early after transplantation can predict subsequent acute rejection and long-term outcome in a large multicenter cohort. METHODS: From 5 international cohorts, 237 patients who underwent IMR measurement early after transplantation were enrolled. The primary outcome was acute allograft rejection (AAR) within 1 year after transplantation. A key secondary outcome was major adverse cardiac events (MACE) (the composite of death, re-transplantation, myocardial infarction, stroke, graft dysfunction, and readmission) at 10 years. RESULTS: IMR was measured at a median of 7 weeks (interquartile range: 3-10 weeks) post-transplantation. At 1 year, the incidence of AAR was 14.4%. IMR was associated proportionally with the risk of AAR (per increase of 1-U IMR; adjusted hazard ratio [aHR]: 1.04; 95% confidence interval [CI]: 1.02-1.06; p < 0.001). The incidence of AAR in patients with an IMR >= 18 was 23.8%, whereas the incidence of AAR in those with an IMR <18 was 6.3% (aHR: 3.93; 95% CI: 1.77-8.73; P = 0.001). At 10 years, MACE occurred in 86 (36.3%) patients. IMR was significantly associated with the risk of MACE (per increase of 1-U IMR; aHR: 1.02; 95% CI: 1.01-1.04; P = 0.005). CONCLUSIONS: IMR measured early after heart transplantation is associated with subsequent AAR at 1 year and clinical events at 10 years. Early IMR measurement after transplantation identifies patients at higher risk and may guide personalized posttransplantation management.

- Objective When the COVID-19 pandemic reached Norway, primary health care had to reorganize to ensure safe patient treatment and maintain infection control. General practitioners (GPs) are key health care providers in the municipalities. Our aim was to explore the experiences and management strategies of Norwegian GPs during the COVID-19 pandemic - over time, and in the context of a sudden organizational change. Design Longitudinal qualitative interview study with two interview rounds. The first round of interviews was conducted from September-December 2020, the second round from January-April 2021. In the first interview round, we performed eight semi-structured interviews with GPs from eight municipalities in Norway. In the second round, five of the GPs were re-interviewed. Consecutive interviews were performed 2-4 months apart. To analyze the data, we used thematic analysis. Results The COVID-19 pandemic required GPs to balance several concerns, such as continuity of care and their own professional efforts. Several GPs experienced challenges in the collaboration with the municipality and in relation to defining their own professional position. Guided by The Norwegian Association of General practitioners, The Norwegian College of General Practice and collegial support, they found viable solutions and ended up with a feeling of having adapted to a new normal. Conclusions Although our study demonstrates that the GPs adapted to the changing conditions, the current municipal health care models are not ideal. There is a need for clarification of responsibilities between GPs and the municipality to facilitate a more coordinated future pandemic response.

- Control interventions (often called "sham," "placebo," or "attention controls") are essential for studying the efficacy or mechanism of physical, psychological, and self-management interventions in clinical trials. This article presents core recommendations for designing, conducting, and reporting control interventions to establish a quality standard in non-pharmacological intervention research. A framework of additional considerations supports researchers' decision making in this context. We also provide a reporting checklist for control interventions to enhance research transparency, usefulness, and rigour.
